Everyday, consumers seek to remedy their interconnection problems by attempting to connect HDMI to Component outputs via a cable linked to their high-def setup. This isn't a simple matter of rearranging your wires or having the right type of connector, unfortunately. Analog and digital are essentially incompatible, much like the fast approaching television broadcasting switch to digital from analog signals, which can be received by rabbit ears or a roof antenna. Because they are not compatible, people wind up being perplexed just like the unfortunate person you see in the commercial.
Analog and digital signals are quite different. Be advised that component video is an analog formatted signal. The voltage signal on the wire is in a wave format on an analog signal, and the changes in the height of the waves are key. In theory, an analog signal has values between zero and the essentially infinite, much like the windshield wipers found on an old Thunderbird vehicle.
In HDMI and DVI, however, this is recorded in a digital way. As you may already know, digital uses ones and zeros and a series of pulses at the same height, and they are either there or they're not. The information is put back together by processing equipment at the other end. So, any device that expects an analog wave from the cable will just interpret the ones and zeros as noise.
What alternatives exist, then? HDMI or DVI output should be used, if it is available on both boxes. The only difference between DVI and HDMI is that HDMI carries video signals in addition to the audio signals. DVI on the other hand, is just as good but carries audio and video on separate cables, so you will have to bear the expense of an additional audio cable. They make a fairly inexpensive HDMI switch box that you can plug multiple HDMI cables into if you were trying to use the Component outputs because your HDMI port was already tied up.
If you heard that HDMI is superior to Component cables, and you would like to convert Component to HDMI, hold on just a moment. There are numerous studies available showing that HDMI cables and digital are superior in theory. This is because there are a lot of potential conversions between the various lines of resolution before it is finally displayed on your television set. For this reason, there are occasions when Component connections deliver a better signal and picture. Most of all, this is the case when cable lengths begin to exceed 25 feet. To determine the cable that delivers you the best picture, try out each of the cables if given the option.
If you have to convert from Component to HDMI cable, converter boxes are available but they usually cost over $200. However, if you go in the opposite direction, you can run into restrictions whenever it comes to High Definition Content Protection. This will prevent you from being able to view HDCP protected sources.
Hopefully it is easy to solve your HDMI to Component problem with one of the HDMI or component cable solutions listed above. If not, it gives you the opportunity to go on a great high-tech shopping spree.
As a home theater system installer, Vic Metten knows that there is a fundamental different between an HDMI cable and a component video cable. However, there are many work-arounds for those who desire to use DVI cables or HDMI cables instead of component video cables and vice versa. All it takes is a little information.
